vagrantでmountエラーの解決方法

Failed to mount folders in Linux guest. This is usually beacuse
the "vboxsf" file system is not available. Please verify that
the guest additions are properly installed in the guest and
can work properly. The command attempted was:

mount -t vboxsf -o uid=`id -u vagrant`,gid=`getent group apache | cut -d: -f3`,dmode=777,fmode=777 /vagrant /vagrant
mount -t vboxsf -o uid=`id -u vagrant`,gid=`id -g apache`,dmode=777,fmode=777 /vagrant /vagrant

こんなエラー。

#解決方法
vboxをリビルドする必要があるようです。

まずsshで入ります

vagrant ssh

リビルド実行します。

sudo /etc/init.d/vboxadd setup

Removing existing VirtualBox non-DKMS kernel modules       [  OK  ]
Building the VirtualBox Guest Additions kernel modules
Building the main Guest Additions module                   [  OK  ]
Building the shared folder support module                  [  OK  ]
Building the OpenGL support module                         [失敗]
(Look at /var/log/vboxadd-install.log to find out what went wrong)
Doing non-kernel setup of the Guest Additions              [  OK  ]

一旦macのコンソールに戻ります。

exit

vagrantを再起動します。

vagrant halt
vagrant up
